I've never seen that model until just now, but they definitely have some similarities. Perhaps it influenced the concept artist who did the original art for the concept. Actually, the original art concept had it being used for a different concept than we originally had with Urgot. We saw Urgot's concept art and revised Urgot's background on the spot; he was originally going to be the executioner badass his bio alludes him to being, but the beast-man and hextech were two great tastes that tasted great together.
